Frequently Asked Questions

What is the communication protocol for this ultrasonic sensor?

The sensor communicates via a UART (TTL-level) serial interface. You can connect its TX and RX pins directly to a microcontroller's UART pins (e.g., Arduino, ESP32, Raspberry Pi). The baud rate, sensor address, and other parameters are configurable through specific serial commands, allowing for daisy-chaining and customization.

What is the minimum and maximum detection distance?

The sensor has a blind zone of ≤3cm, meaning objects closer than this may not be detected reliably. The effective measurement range is from 3cm up to 500cm for flat, reflective surfaces. Accuracy is specified as 1cm + (0.3% of the measured distance), ensuring high precision across its full range.

Can I power this sensor with 5V from an Arduino?

Yes, the sensor's wide operating voltage range of 3.3V to 24V DC includes standard 5V logic levels. You can safely power it from an Arduino's 5V pin. Its UART interface operates at TTL levels, making it directly compatible with 5V or 3.3V microcontroller systems without requiring a logic level shifter.

How does the sensor handle interference from other ultrasonic devices?

The module incorporates intelligent acoustic processing technology that identifies and filters out same-frequency ultrasonic interference. This significantly reduces the probability of false readings in environments with multiple ultrasonic sensors or other sources of acoustic noise, ensuring stable and reliable data output.

Is this sensor suitable for outdoor use?

Yes, the sensor is designed with a high waterproof grade and dustproof construction, making it suitable for use in damp or dusty outdoor environments typical in robotics, parking systems, and industrial automation. Its wide operating temperature range further supports reliable performance in varying climatic conditions.
